FLY ING-MACHINE.

To all whom it may concern:

Be it known that I, LOUIS L. CRANE, a citizen of the United States, residing at Brooklyn, in the .county of Kings, city and State of New York, have invented certain new and useful Improvements in Flying- Machines, of which the following is a clear,

neverthe ess of demonstrating full, and exact description.

This inventionrelates to flying machines, containing principles which may be used to advantage 1n man-carrying, engine propellin vehlcles. It is particularly applicable an desi ed for use as a toy, but is capable aeronautic principles tothe users thereof.

Incarrying out my invention I make use l of an elongated frame carrying the propelv-is a plan view of an aeroplane constructed accordlng to my invention. F ig. 2 isa side elevation thereof. Fig. 3 isa front eleval held in triangular position in theV journal ling means, preferably in the form of strands of twisted rubber bands. A journal plate carries the motor shaft with a propeller mounted thereon in front of the aeroplane. The plane is preferably of three parts; two forward wings identical on each side of the center, with an u ward tilt, and a third; preferably as a trlan lar tail having the apex of the triangle a ove the lowest point o the forwardwmgs. f

The scope of my invention will be pointed out in the claims. l

In carrying out m'yinvention: Figure 1 tion with the propeller removed.

. AS shown in the drawings, the/main frame' 1s composed of longitudinal rods 1, 2 and 3 platev 6 at one end and bound together at 4f, whereby a tripod is produced forming an elongated chamber'for the motive power. Posts `17 and 16 near the tail of the frame serve to space it, and to form a post, around which strands of rubber 15 may be stationarily' secured. At right angles to the end of the frame, I secure a cross bar 9 carrying the triangular tail 10 secured at its. apex to one of the members of the tripod frame.

In the journal late 6I mount a shaft 14, to oneend of wliich 'is looped the rubber bands 15 within the tripod frame, and to the free end of which I secure the ropeller blades 13; the outer end of the shaflz) 14 may be threaded to Vscrew into the rod connecting the propeller blades. Across the journal plate I mount at right angles a bar 7 extending each side of the tripod frame, and

below such rod and to the rear f thereof the tilt of the wings 11 and 12 when the propeller is in motion, serve to hold the maehlne up 1n the air.

be put under I am aware that toys have heretofore been made which will ily vertically by propeller blades under torsion, and I do not claim such as my invention. v

In carrying out this invention, details of construction may `be varied from those shown, and yet the essence of the invention be retained; some parts might be employed without others, and 'new features thereof might be combined with elements old in the art in diverse ways, although the herein described type is regarded as embodying substantial improvements over such modifications.

As many changes could be made. in the above construction,` and many apparently widely different embodiments of the invention could be made without departin from the scope thereof, it is intended that a l mat- Vter contained in the above description or shownin the accompanying drawings shall be interpreted in an illustrative and not in a limiting sense. It is furthermore desired to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which as -a matter of language might be said to fall therebetween.

I claim as my invention:

1. The herein described aeroplane, consisting of arotating shaft, a propeller thereon, a twlsted torsional drivin means for the propeller, an elongated rame carrying the same, cross bars Ito the frame, side wings and a tail, the side wings having a slant from the upper bar to a lower bar, the tail being of triangular shape and secured at its apex to the frame, forward of the cross bar therefor.

2. -The herein described aeroplane, having an elongated frame of a number of rods spaced apart at the front end and joined to-A ether at the rear end, a journal plate at the ront end, a shaft therein, a propeller on the shaft in front of the plate, torsional driving means Within the frame, tilted side Wings on each side of the forward end of the frame, a triangular tail piece having its apex ixed to one of the elongated rods, anda cross bar near the end of the :frame to which the other end of the tail is secured. 3. The herein described aeroplane consistlnxgi of a journal plate, three longitudinal r s, one secured at the upper part of the plate, the other two at the bottom, the free @meer ends of such rods being joined together to form a tripod, a torsional driving means in the shape of twisted rubber bands Within the tripod, ashaft in the platea propeller in front of the shaft and secured thereto, a pair of tilted Wings, one on each side of the forward part of the frame, and a triangular tail at the rear thereof.

Signed at New York city this 20 day of December 1909.
